Abstract (en)

[origin: EP0258160A2] Derivatives of formula: <IMAGE> - X is a halogen, preferably fluorine, bromine or chlorine, atom, or an alkyl or alkoxy group containing from 1 to 12 carbon atoms, preferably from 1 to 4 carbon atoms and being optionally mono- or polyhalogenated (especially CF3 group), or a cyano group in the case where R3 and/or R4 correspond to the hydrogen atom, - n is an integer, positive or zero, smaller than 6, preferably equal to 2, it being understood that when n is greater than 1, the substituents X may be either identical or different, - m = 0 or 1, - Y corresponds to an atom or group capable of being removed by means of a nucleophilic substitution, optionally after suitable intermediate conversion. Their agriculturally acceptance salts. Use of these derivatives as intermediates in the process for the preparation of tetrahydrofuran containing a triazole group, which can be used as fungicides.
